DETAILED DESCRIPTION OF THE INVENTION

Other objects and aspects of the invention will become apparent from thefollowing description of the embodiments with reference to theaccompanying drawings, which is set forth hereinafter.

FIG. 3 is a view illustrating caller information display system inaccordance with a preferred embodiment of the present invention.Referring to FIG. 3, the caller information display system includes acaller terminal 310, a service system 320 and a receiver terminal 330.In the caller information display system of FIG. 3, caller informationis transmitted from the caller terminal 310 to the receiver terminal 330during a call.

The caller terminal 310 stores caller information such as pictures,avatars and moving pictures of a calling party in a predetermined memoryspace thereof. The caller terminal 310 sends a call origination messageand is allocated a traffic channel. After a service connection iscompleted, the caller terminal 310 transmits caller informationpreviously set to the receiver terminal through a traffic channel duringa call.

The service system 320 receives the call origination message and sends ageneral page message to the receiver terminal 330. When a page responsemessage is received from the receiver terminal 330, the service system320 establishes a communication between the caller terminal 310 and thereceiver terminal 330.

The receiver terminal 330 receives the general page message and sends apage response message to be allocated a traffic channel. When acommunication is established, the receiver terminal 330 receives callerinformation through the service system 320 from the caller terminal 310during a call. Preferably, the received call information isautomatically stored by linking a telephone number contained in the datawith a telephone number stored in a telephone directory. The receiverterminal 330 displays the stored caller information on a display screenwhen the caller terminal 310 makes a phone call.

FIG. 4 is a flowchart illustrating a method for displaying callerinformation in accordance with a preferred embodiment of the presentinvention. Referring to FIG. 4, a user as a caller newly registers orupdates caller information such as pictures, avatars or moving pictures,and selects or designates a receiver terminal or a group of receiverterminals which will receive the caller information at step S401.Selecting or designating the receiver terminals can be done during acall.

When a user as a caller selects a receiver terminal 330 to make a phonecall (step S403), the caller terminal 310 determines whether or notcaller information needs to be registered or updated for the receiverterminal 330 at step S405. That is, in the step of S405, the callerterminal 310 checks whether or not newly renewed caller information istransmitted to the selected receiver terminal 330.

In the case that caller information needs to be registered or updated inthe receiver terminal 330, when the service system 320 establishes acommunication between the caller terminal 310 and the receiver terminal330 at step S407, the caller terminal 310 transmits the callerinformation to the receiver terminal 330 at step S409. The receiverterminal 330 receives the data including the caller information from theservice system 320 through the forward traffic channel and stores thecaller information to be linked with a phone number listed in atelephone directory at step S411, thereby registering or updating thecaller information at step S413.

Here, if a phone number of the caller terminal 310 is not a numberstored in the telephone directory of the receiver terminal 330, thephone number of the caller terminal 310 is temporarily stored in apredetermined memory space and becomes a state waiting for aregistration of the caller information by a receiver, and thereafter thecaller information is registered by a receiver. For example, a messageasking a registration can be displayed on a screen of the receiverterminal.

If a phone number of the caller terminal 310 is a number stored in thetelephone directory of the receiver terminal 330, the caller informationis internally stored to be linked with a phone number of the callerterminal 310 while the previously set call information is externallydisplay on a display screen, thereby updating the call information.

Meanwhile, in the case that there is no need that caller information isregistered or updated in the receiver terminal 330, when a paging signalis received, the receiver terminal 330 displays caller informationlinked with a telephone number contained in the paging signal at stepS417 before a call begins at step S419. Therefore, a user as a receivercan easily identify a caller.

As a modification of the caller information display system and method ofFIGS. 3 and 4, caller information is stored in the service system 320 inadvance by a predetermined method (e.g., Internet), and receivers aredesignated, and thereafter when a communication is established betweenthe caller terminal 310 and the receiver terminal 330, the callerinformation is transmitted to the receiver terminal 330 and stored to belinked with a telephone number stored in a telephone directory.

FIG. 5 is a view illustrating caller information display system inaccordance with a preferred embodiment of the present invention.Referring to FIG. 5, the caller information display system includes acaller terminal 510, a service system 520 and a receiver terminal 530.The caller information is transmitted to the receiver terminal 530 whenthe receiver terminal 530 is in a state that caller information can bereceived, e.g., during a call or in an idle state.

The caller terminal 510 serves to transmit to the service server 520 adata packet including caller information such as pictures, avatars andmoving pictures of the calling party and telephone numbers of designatedreceiver terminals 530.

The service system 520 temporarily stores the data packet, and transmitsthe caller information to the designated receiver terminal 530 when thedesignated receiver terminal 530 is in a state that can receive thecaller information.

The receiver terminal 530 receives the caller information from theservice system 520 and stores the caller information to be linked with atelephone number stored in the telephone directory.

FIG. 6 is a flowchart illustrating a method for displaying callerinformation in accordance with a preferred embodiment of the presentinvention. Referring to FIG. 6, a user as a caller registers or updatescaller information such as pictures, avatars or moving pictures at stepS601. A receiver terminal 530 or a group of receiver terminals 530 aredesignated at step S603. The caller terminal 510 transmits to theservice system 520 caller information and a telephone number of thedesignated receiver terminal 530 in the form of preferably data packetat step S605.

The service system 520 temporarily stores a data packet received fromthe caller terminal 510 and transmits to the designated receiverterminal 530 caller information together with a caller's telephonenumber when the designated receiver terminal 530 is in a state that canreceive caller information at step S607. The receiver terminal 530stores the caller information to be linked with a caller's telephonenumber listed in a telephone directory at step S609, thereby registeringor updating caller information. Thereafter, when the receiver terminal530 receives a paging signal, steps S415 to S419 of FIG. 4 areperformed.
